Description
この発明は、被固定部材を支持部材に対して盗難を防止した状態で固定することができるネジセットに関するものである。 The present invention relates to a screw set capable of fixing a member to be fixed to a support member in a state in which the member is prevented from being stolen.
従来、この種の被固定部材の盗難防止技術としては、例えば特許文献１に開示されるような技術が提案されている。この従来技術においては、支持部材上に被固定部材を支持するとともに、被固定部材の上面側からのボルトまたはナットの締め付けにより被固定部材を支持部材に固定した状態で、ボルトの頭部またはナットに合成樹脂よりなるキャップ状の盗難防止具を被覆嵌着している。この盗難防止具の外周面は円筒状をなすように形成され、工具を用いてもボルトまたはナットを回転できないようになっている。 Conventionally, as a technique for preventing theft of this type of fixed member, for example, a technique disclosed in Patent Document 1 has been proposed. In this prior art, a bolt head or nut is supported in a state where the member to be fixed is supported on the support member and the member to be fixed is fixed to the support member by tightening the bolt or nut from the upper surface side of the member to be fixed. A cap- shaped antitheft device made of synthetic resin is covered with a cover. The outer peripheral surface of the antitheft tool is formed in a cylindrical shape, and the bolt or nut cannot be rotated even if a tool is used.
ところが、この従来の盗難防止方法においては、ボルトまたはナットにより被固定部材を支持部材上に固定した後、ハンマ等を用いてボルトの頭部またはナットに盗難防止具を嵌着する必要がある。このため、支持部材に対する被固定部材の固定作業が煩雑で時間がかかるという問題があった。 However, in this conventional antitheft method, it is necessary to fix the member to be fixed on the support member with a bolt or nut and then fit the antitheft tool to the head or nut of the bolt using a hammer or the like. For this reason, there has been a problem that the fixing work of the fixed member to the support member is complicated and takes time.
この発明は、このような従来の技術に存在する問題点に着目してなされたものである。その目的は、被固定部材を支持部材に対して盗難防止状態に容易に固定することができるネジセットを提供することにある。 The present invention has been made paying attention to such problems existing in the prior art. An object of the present invention is to provide a screw set that can easily fix a member to be fixed to a support member in an anti-theft state.
上記の目的を達成するために、このネジセットは、固定用ネジ部を有するネジ本体と、そのネジ本体の外周に形成した雄ネジ部に螺合されるナットとを備え、前記雄ネジ部及びナットの雌ネジ部の少なくとも一方には、その両ネジ部間の螺合力を前記固定用ネジ部における螺合力より弱くするための滑動手段を設けたことを特徴としている。 In order to achieve the above object, the screw set includes a screw main body having a fixing screw portion, and a nut screwed into a male screw portion formed on an outer periphery of the screw main body, the male screw portion and At least one of the female screw portions of the nut is provided with sliding means for making the screwing force between the two screw portions weaker than the screwing force in the fixing screw portion.
従って、このネジセットの使用時には、ネジ本体の雄ネジ部にナットの雌ネジ部を螺合させることによって、ネジ本体とナットとを一体化した状態で、ナットに通常の工具を係合させて、ネジ本体の固定用ネジ部を締め付ければ、被固定部材を支持部材に対して容易に固定することができる。この固定状態においては、ネジ本体の雄ネジ部とナットの雌ネジ部との間の螺合力が固定用ネジ部における螺合力より弱くなっているため、ナットに通常の工具を係合させてネジセット全体を弛緩回転させようとしても、ナットのみがネジ本体に対して弛緩回転されて、ネジ本体の固定用ネジ部は締め付け状態に保持されている。よって、被固定部材を支持部材に対して容易に固定することができるとともに、簡単な構成によって被固定部材の盗難を的確に防止することができる。 Therefore, when using this screw set, by engaging the female screw part of the nut with the male screw part of the screw main body, with the screw main body and the nut integrated, a normal tool is engaged with the nut. If the fixing screw portion of the screw body is tightened, the fixed member can be easily fixed to the support member. In this fixed state, the screwing force between the male screw part of the screw body and the female screw part of the nut is weaker than the screwing force in the fixing screw part. Even if the entire set is loosely rotated, only the nut is loosely rotated with respect to the screw main body, and the fixing screw portion of the screw main body is held in a tightened state. Therefore, the fixed member can be easily fixed to the support member, and the fixed member can be prevented from being stolen with a simple configuration.
前記のネジセットによれば、被固定部材を支持部材に対して盗難防止状態に容易に固定することができるという効果を発揮する。 According to the above-described screw set, an effect is obtained that the fixed member can be easily fixed to the support member in the anti-theft state.
（第１実施形態）
以下、雌ネジセットに具体化した第１実施形態を図１〜図３に従って説明する。
図１及び図２示すように、この実施形態の雌ネジセット１１には、ネジ本体１２とナット１３とが備えられている。ナット１３は、レンチ等の汎用の通常工具に対応するように六角形状をなしている。ネジ本体１２の中心には、雌ネジよりなる固定用ネジ部１２１が形成されている。ネジ本体１２の外周には、ナット１３の雌ネジ部１３１を螺合させる雄ネジ部１２２が形成されている。ネジ本体１２の端縁には、専用工具に対応する形状のフランジ１２３が形成されている。本実施形態では、専用工具の使用を可能にするためにフランジ１２３はその周面の３箇所に平面部１２４を備えている。そして、雌ネジセット１１は、ネジ本体１２の雄ネジ部１２２にナット１３が螺合された状態で市場に流通される。
(First embodiment)
Hereinafter, a first embodiment embodied in a female screw set will be described with reference to FIGS.
As shown in FIGS. 1 and 2, the female screw set 11 of this embodiment includes a screw body 12 and a nut 13. The nut 13 has a hexagonal shape so as to correspond to a general-purpose normal tool such as a wrench. At the center of the screw body 12, a fixing screw portion 121 made of a female screw is formed. On the outer periphery of the screw main body 12, a male screw portion 122 for screwing the female screw portion 131 of the nut 13 is formed. A flange 123 having a shape corresponding to the dedicated tool is formed on the edge of the screw body 12. In the present embodiment, in order to enable the use of a dedicated tool, the flange 123 includes flat portions 124 at three locations on the peripheral surface thereof. The female screw set 11 is distributed to the market in a state where the nut 13 is screwed to the male screw portion 122 of the screw main body 12.
前記ネジ本体１２の雄ネジ部１２２とナット１３の雌ネジ部１３１との少なくとも一方（本実施形態では一方であって、ナット１３にのみ）には、その両ネジ部１２２，１３１間の螺合力を前記固定用ネジ部１２１における螺合力より弱くするための滑動手段としての滑動構成１４が設けられている。本実施形態では、この滑動構成１４がフッ素コーティングよりなっている。 At least one of the male screw portion 122 of the screw main body 12 and the female screw portion 131 of the nut 13 (one in this embodiment, only the nut 13) has a screwing force between the screw portions 122 and 131. Is provided with a sliding structure 14 as a sliding means for making the fixing screw portion 121 weaker than the screwing force. In this embodiment, the sliding structure 14 is made of a fluorine coating.
次に、前記のように構成された雌ネジセットの使用方法について説明する。
図３に示すように、この雌ネジセット１１を用いて、太陽電池パネル等の被固定部材１５を支持部材１６上に固定する場合には、例えば支持部材１６上に被固定部材１５を支持した状態で、支持部材１６の下面側から支持部材１６及び被固定部材１５のボルト挿通孔１６１，１５１に固定用ボルト１７を挿通する。この状態で、被固定部材１５の上面側から、固定用ボルト１７の先端に座金１８を介して雌ネジセット１１を螺合させる。なお、この座金１８は用いられないこともある。この場合、雌ネジセット１１は、あらかじめネジ本体１２の雄ネジ部１２２にナット１３の雌ネジ部１３１を螺合させることによって、ネジ本体１２とナット１３とが一体化されている。そして、ナット１３に汎用の通常工具を係合させて締め付け方向に回転させることにより、ネジ本体１２の固定用ネジ部１２１が固定用ボルト１７に締め付けられて、被固定部材１５が支持部材１６に対して固定される。
Next, a method for using the female screw set configured as described above will be described.
As shown in FIG. 3, when the fixed member 15 such as a solar cell panel is fixed on the support member 16 using the female screw set 11, for example, the fixed member 15 is supported on the support member 16. In this state, the fixing bolts 17 are inserted into the bolt insertion holes 161 and 151 of the supporting member 16 and the fixed member 15 from the lower surface side of the supporting member 16. In this state, the female screw set 11 is screwed into the tip of the fixing bolt 17 via the washer 18 from the upper surface side of the fixed member 15. The washer 18 may not be used. In this case, in the female screw set 11, the screw main body 12 and the nut 13 are integrated by previously screwing the female screw portion 131 of the nut 13 into the male screw portion 122 of the screw main body 12. Then, by engaging a general-purpose normal tool with the nut 13 and rotating in the tightening direction, the fixing screw portion 121 of the screw body 12 is tightened to the fixing bolt 17, and the fixed member 15 is attached to the support member 16. It is fixed against.
この被固定部材１５の固定状態においては、滑動構成１４によりネジ本体１２の雄ネジ部１２２とナット１３の雌ネジ部１３１との間の螺合力が、固定用ボルト１７に対する固定用ネジ部１２１の螺合力より弱くなっている。このため、ナット１３に通常の工具を係合させて雌ネジセット１１全体を弛緩回転させようとしても、ナット１３がネジ本体１２に対して弛緩回転されるのみで、ネジ本体１２の固定用ネジ部１２１は固定用ボルト１７に対して締め付け状態に保持されている。よって、雌ネジセット１１が固定用ボルト１７から取り外されて、太陽電池パネル等の被固定部材１５が盗難されるおそれはない。 In the fixed state of the fixed member 15, the screwing force between the male screw portion 122 of the screw main body 12 and the female screw portion 131 of the nut 13 is caused by the sliding configuration 14 so that the fixing screw portion 121 is fixed to the fixing bolt 17. It is weaker than the screwing force. For this reason, even if an ordinary tool is engaged with the nut 13 to loosen and rotate the entire female screw set 11, the nut 13 is only loosely rotated with respect to the screw body 12, and the fixing screw for the screw body 12 is fixed. The portion 121 is held in a tightened state with respect to the fixing bolt 17. Therefore, there is no possibility that the female screw set 11 is removed from the fixing bolt 17 and the fixed member 15 such as the solar battery panel is stolen.
なお、被固定部材１５等の補修点検等を行う場合には、ネジ本体１２上のフランジ１２３に専用工具を係合させて回転操作すれば、ネジ本体１２の固定用ネジ部１２１が固定用ボルト１７に対して弛緩されて、被固定部材１５を支持部材１６上から取り外すことができる。 When repairing and inspecting the fixed member 15 or the like, if the special tool is engaged with the flange 123 on the screw main body 12 and rotated, the fixing screw portion 121 of the screw main body 12 is fixed to the fixing bolt. The member to be fixed 15 can be detached from the support member 16 by being relaxed with respect to the member 17.
従って、この実施形態によれば、以下のような効果を得ることができる。
（１） この実施形態の雌ネジセットにおいては、固定用ネジ部１２１を有するネジ本体１２と、そのネジ本体１２の外周に形成した雄ネジ部１２２に螺合されるナット１３とが備えられている。ネジ本体１２には、専用工具に対応する形状のフランジ１２３が形成されている。雄ネジ部１２２及びナット１３の雌ネジ部１３１の少なくとも一方には、その両ネジ部１２２，１３１間の螺合力を固定用ネジ部１２１における螺合力より弱くするための滑動構成１４が施されている。
Therefore, according to this embodiment, the following effects can be obtained.
(1) The female screw set of this embodiment includes a screw main body 12 having a fixing screw portion 121 and a nut 13 screwed into a male screw portion 122 formed on the outer periphery of the screw main body 12. Yes. The screw body 12 is formed with a flange 123 having a shape corresponding to the dedicated tool. At least one of the male screw part 122 and the female screw part 131 of the nut 13 is provided with a sliding structure 14 for making the screwing force between the screw parts 122 and 131 weaker than the screwing force in the fixing screw part 121. Yes.
このため、ネジ本体１２とナット１３とを一体化した状態で、ナット１３に汎用の通常工具を係合させて、ネジ本体１２の固定用ネジ部１２１を締め付けることにより、被固定部材１５を支持部材１６に対して容易に固定することができる。この固定状態においては、ネジ本体１２の雄ネジ部１２２とナット１３の雌ネジ部１３１との間の螺合力が固定用ネジ部１２１における螺合力より弱くなっているため、通常工具により雌ネジセット１１全体を弛緩回転させようとしても、ナット１３のみがネジ本体１２に対して弛緩回転される。よって、被固定部材１５を支持部材１６に対して容易に固定することができるとともに、簡単な構成によって被固定部材１５の盗難を適切に防止することができる。 For this reason, with the screw body 12 and the nut 13 integrated, a general-purpose normal tool is engaged with the nut 13 and the fixing screw portion 121 of the screw body 12 is tightened to support the fixed member 15. It can be easily fixed to the member 16. In this fixed state, the screwing force between the male screw part 122 of the screw body 12 and the female screw part 131 of the nut 13 is weaker than the screwing force in the fixing screw part 121. Even if the whole 11 is to be loosely rotated, only the nut 13 is loosely rotated with respect to the screw body 12. Therefore, the fixed member 15 can be easily fixed to the support member 16, and the fixed member 15 can be appropriately prevented from being stolen with a simple configuration.
（２） この実施形態においては、前記滑動構成１４がフッ素コーティングからなっている。このため、部品点数が増えることなく、簡単な滑動構成１４によって、ネジ本体１２の雄ネジ部１２２とナット１３の雌ネジ部１３１との間の螺合力を固定用ネジ部１２１における螺合力より弱くなるように設定することができる。 (2) In this embodiment, the sliding structure 14 is made of a fluorine coating. For this reason, the screwing force between the male screw part 122 of the screw body 12 and the female screw part 131 of the nut 13 is weaker than the screwing force in the fixing screw part 121 by the simple sliding configuration 14 without increasing the number of parts. Can be set to
（第２実施形態）
次に、雄ネジセットに具体化した第２実施形態を前記第１実施形態と異なる部分を中心に説明する。
(Second Embodiment)
Next, a second embodiment embodied in a male screw set will be described with a focus on differences from the first embodiment.
図４〜図６に示すように、この第２実施形態の雄ネジセット２１には、ネジ本体１２とナット１３とが備えられている。ネジ本体１２の一側には、雄ネジよりなる固定用ネジ部１２１が突設されている。ネジ本体１２の頭部側の他側には、ナット１３の雌ネジ部１３１を螺合させる雄ネジ部１２２が形成されている。ネジ本体１２の中間部には、専用工具に対応する形状のフランジ１２３が形成されている。そして、前記第１実施形態の場合と同様に、ネジ本体１２の雄ネジ部１２２とナット１３の雌ネジ部１３１との少なくとも一方（実施形態では一方であって、ナット１３にのみ）には、その両ネジ部１２２，１３１間の螺合力を前記固定用ネジ部１２１における螺合力より弱くするためのフッ素コーティングよりなる滑動構成１４が設けられている。そして、雄ネジセット２１は、ネジ本体１２の頭部側の雄ネジ部１２２にナット１３が螺合された状態で市場に流通される。 As shown in FIGS. 4 to 6, the male screw set 21 of the second embodiment includes a screw body 12 and a nut 13. On one side of the screw main body 12, a fixing screw portion 121 made of a male screw protrudes. On the other side of the head side of the screw main body 12, a male screw portion 122 for screwing the female screw portion 131 of the nut 13 is formed. A flange 123 having a shape corresponding to the dedicated tool is formed at an intermediate portion of the screw body 12. As in the case of the first embodiment, at least one of the male screw portion 122 of the screw main body 12 and the female screw portion 131 of the nut 13 (one in the embodiment, only the nut 13), A sliding structure 14 made of fluorine coating is provided to make the screwing force between the screw parts 122 and 131 weaker than the screwing force in the fixing screw part 121. The male screw set 21 is distributed to the market in a state where the nut 13 is screwed to the male screw portion 122 on the head side of the screw main body 12.
図６に示すように、この雄ネジセット２１を用いて、被固定部材１５を支持部材１６上に固定する場合には、支持部材１６上に被固定部材１５を支持した状態で、被固定部材１５の上面側から被固定部材１５及び支持部材１６のボルト挿通孔１５１，１６１に、座金１８を介して雄ネジセット２１の固定用ネジ部１２１を挿通する。この場合も、座金１８は用いられない場合がある。この状態で、支持部材１６の下面側から固定用ネジ部１２１に固定用ナット２２を螺合させる。この場合、雄ネジセット２１は、予めネジ本体１２の雄ネジ部１２２にナット１３の雌ネジ部１３１を螺合させることによって、ネジ本体１２とナット１３とが一体化されている。そして、ナット１３に通常の工具を係合させて締め付け方向に回転させることにより、ネジ本体１２の固定用ネジ部１２１が固定用ナット２２に締め付けられて、被固定部材１５が支持部材１６に対して固定される。 As shown in FIG. 6, when the fixed member 15 is fixed on the support member 16 using the male screw set 21, the fixed member 15 is supported in a state where the fixed member 15 is supported on the support member 16. The fixing screw portion 121 of the male screw set 21 is inserted through the washer 18 into the bolt insertion holes 151 and 161 of the fixed member 15 and the support member 16 from the upper surface side of 15. Also in this case, the washer 18 may not be used. In this state, the fixing nut 22 is screwed into the fixing screw portion 121 from the lower surface side of the support member 16. In this case, in the male screw set 21, the screw main body 12 and the nut 13 are integrated by screwing the female screw portion 131 of the nut 13 into the male screw portion 122 of the screw main body 12 in advance. Then, by engaging a normal tool with the nut 13 and rotating it in the tightening direction, the fixing screw portion 121 of the screw main body 12 is tightened to the fixing nut 22, and the fixed member 15 is fixed to the support member 16. Fixed.
この被固定部材１５の固定状態においては、前記第１実施形態の場合と同様に、雄ネジセット２１のナット１３に通常の工具を係合させて雄ネジセット２１全体を弛緩回転させようとしても、ナット１３がネジ本体１２に対して弛緩回転されるのみで、ネジ本体１２の固定用ネジ部１２１は固定用ナット２２に対して締め付け状態に保持されている。よって、雄ネジセット２１が固定用ナット２２から取り外されて、被固定部材１５が盗難されるおそれはない。 In the fixed state of the fixed member 15, even if an ordinary tool is engaged with the nut 13 of the male screw set 21 to loosely rotate the male screw set 21 as in the case of the first embodiment. Only the nut 13 is loosely rotated with respect to the screw main body 12, and the fixing screw portion 121 of the screw main body 12 is held in a tightened state with respect to the fixing nut 22. Therefore, there is no possibility that the male screw set 21 is removed from the fixing nut 22 and the fixed member 15 is stolen.
被固定部材１５等の補修点検等を行う場合には、ネジ本体１２上のフランジ１２３に専用工具を係合させて回転操作すれば、ネジ本体１２の固定用ネジ部１２１がナット２２に対して弛緩されて、被固定部材１５を支持部材１６上から取り外すことができる。 When repairing or inspecting the fixed member 15 or the like, the fixing screw portion 121 of the screw main body 12 can be moved relative to the nut 22 by engaging a dedicated tool with the flange 123 on the screw main body 12 and rotating it. After being relaxed, the fixed member 15 can be removed from the support member 16.
従って、この第２実施形態において、前記第１実施形態における（１）及び（２）に記載の効果とほぼ同様な効果を得ることができる。
（変更例）
なお、この実施形態は、次のように変更して具体化することも可能である。
Therefore, in the second embodiment, it is possible to obtain substantially the same effect as the effects described in (1) and (2) in the first embodiment.
(Example of change)
In addition, this embodiment can also be changed and embodied as follows.
・ 雌ネジセット１１，雄ネジセット２１を構成するナット１３をキャップ状の袋ナットによって構成すること。
・ 支持部材１６上に固定用ボルト１７を突出固定し、その固定用ボルト１７に対して雌ネジセット１１上の雌ネジよりなる固定用ネジ部１２１を螺合すること。
-The nut 13 constituting the female screw set 11 and the male screw set 21 is constituted by a cap-shaped cap nut.
The fixing bolt 17 is protruded and fixed on the support member 16, and the fixing screw portion 121 made of the female screw on the female screw set 11 is screwed to the fixing bolt 17.
・ 固定用ナット２２に代えて支持部材１６に固定用雌ネジを形成し、その固定用雌ネジに対して雄ネジセット２１上の雄ネジよりなる固定用ネジ部１２１を螺合すること。
・ 滑動手段として、前記実施形態のフッ素コーティングとは別の構成を採用すること。例えば、フッ素コーティングに代えて二硫化モリブデンや、潤滑油等の摩擦係数が低い材料や潤滑性を発揮する材料を用いること。
A fixing female screw is formed on the support member 16 instead of the fixing nut 22, and a fixing screw portion 121 made of a male screw on the male screw set 21 is screwed into the fixing female screw.
-As a sliding means, the structure different from the fluorine coating of the said embodiment is employ | adopted. For example, instead of fluorine coating, use a material with low friction coefficient such as molybdenum disulfide, lubricating oil, or a material that exhibits lubricity.
・ 同じく滑動手段として、前記実施形態のフッ素コーティング以外の構成、例えば、ネジ本体１２の雄ネジ部１２２とナット１３の雌ネジ部１３１との間のクリアランスを、ネジ本体１２の固定用ネジ部１２１と固定用ボルト１７あるいは固定用ナット２２との間のクリアランスより大きくすること。あるいは、ネジ本体１２の固定用ネジ部１２１と固定用ボルト１７あるいは固定用ナット２２との間の一部または全体に接着剤を介在させて、外し難くし、結果としてネジ本体１２の雄ネジ部１２２とナット１３の雌ネジ部１３１との間の螺合力を他の部分の螺合力より相対的に弱くすること。 Similarly, as the sliding means, a configuration other than the fluorine coating of the above-described embodiment, for example, a clearance between the male screw portion 122 of the screw main body 12 and the female screw portion 131 of the nut 13 is used as the fixing screw portion 121 of the screw main body 12. And the clearance between the fixing bolt 17 and the fixing nut 22. Alternatively, an adhesive is interposed between a part or the whole between the fixing screw part 121 of the screw main body 12 and the fixing bolt 17 or the fixing nut 22 to make it difficult to remove. As a result, the male screw part of the screw main body 12 The screwing force between 122 and the female screw part 131 of the nut 13 is made relatively weaker than the screwing force of other parts.
・ ネジ本体１２のフランジ１２３と、そのフランジ１２３と当たる座金１８（座金１８が設けられない場合は、被固定部材１５）との少なくとも一方にネジ本体１２の回転に抵抗を与える手段を設けること。この抵抗を与える手段としては、フランジ１２３や、座金１８あるいは被固定部材１５の当接面に凹凸を形成したり、粗面加工を施したり、または、フランジ１２３と、座金１８あるいは被固定部材１５との間にゴム等の摩擦係数の高い材料のものを介在させたりすることが考えられる。この場合も、結果としてネジ本体１２の雄ネジ部１２２とナット１３の雌ネジ部１３１との間の螺合力を他の部分の螺合力より相対的に弱くすることになる。 -At least one of the flange 123 of the screw main body 12 and the washer 18 that contacts the flange 123 (or the fixed member 15 when the washer 18 is not provided) is provided with a means for imparting resistance to the rotation of the screw main body 12. As means for giving this resistance, the contact surface of the flange 123, the washer 18 or the member to be fixed 15 is formed with irregularities or roughened, or the flange 123 and the washer 18 or the member to be fixed 15 are provided. It is conceivable that a material having a high friction coefficient such as rubber is interposed between the two. Also in this case, as a result, the screwing force between the male screw part 122 of the screw main body 12 and the female screw part 131 of the nut 13 becomes relatively weaker than the screwing force of other parts.
・ 専用工具のための平面部１２４の数を２箇所以下または４箇所以上に変更すること。
・ フランジ１２３の外周を平面部１２４のみで構成すること。この場合、フランジ１２３の外周形状を汎用の通常工具を使用できない形状にする。
-Change the number of plane parts 124 for the dedicated tool to 2 or less or 4 or more.
-The outer periphery of the flange 123 should be composed only of the flat portion 124. In this case, the outer peripheral shape of the flange 123 is made a shape in which a general-purpose normal tool cannot be used.
・ フランジ１２３の外周を星形等の凹凸形状にすること。
・ フランジ１２３の外周の専用工具のための平面部１２４を無くすこと。従って、フランジ１２３の外周は円形になる。
-Make the outer periphery of the flange 123 into an uneven shape such as a star shape.
-The flat part 124 for the dedicated tool on the outer periphery of the flange 123 is eliminated. Therefore, the outer periphery of the flange 123 is circular.
・ 図７及び図８に示すように、フランジ１２３の外周の平面部１２４以外の部分であって、被固定部材１５の反対側の縁部にコーナが形成されないように丸く形成すること。あるいは、２点鎖線Ｌで示すように、同部分をナット１３側に向かって収束するテーパ状にすること。このようにすれば、通常工具をより使用し難くなる。なお、これらの構成を平面部１２４を有しない構成において具体化してもよい。 As shown in FIGS. 7 and 8, the flange 123 is formed in a round shape so that a corner is not formed on the opposite edge of the fixed member 15 other than the flat portion 124 on the outer periphery of the flange 123. Alternatively, as indicated by a two-dot chain line L, the same portion is tapered so as to converge toward the nut 13 side. If it does in this way, it will become difficult to use a normal tool more. In addition, you may materialize these structures in the structure which does not have the plane part 124. FIG.
・ 図９及び図１０に示すように、ネジ本体１２のフランジ１２３を省略し、ナット１３と被固定部材１５との間に間隔２５が形成されるようにすること。この構成の場合、雄ネジ部１２２の下部に無ネジ部１２５を設けたり、雄ネジ部１２２の端面にナット１３の内奥面が当たるようにしたりすることにより前記間隔２５が形成される。この構成の場合、雌ネジセット１１や雄ネジセット２１を組み付けた後は、前記各実施形態と同様に、ナット１３のみが弛緩回転されて、盗難が防止される。そして、この図９及び図１０の構成においては、ナット１３はその外周面が円形に構成され、ナット１３の頂面にドライバのためのプラス，マイナス等の溝１３２やレンチのための六角孔を設けることが好ましい。 As shown in FIGS. 9 and 10, the flange 123 of the screw body 12 is omitted, and a gap 25 is formed between the nut 13 and the fixed member 15. In the case of this configuration, the interval 25 is formed by providing the non-threaded portion 125 below the male screw portion 122 or by allowing the inner back surface of the nut 13 to abut the end surface of the male screw portion 122. In the case of this configuration, after assembling the female screw set 11 and the male screw set 21, only the nut 13 is loosely rotated and theft is prevented, as in the above embodiments. 9 and 10, the nut 13 has a circular outer peripheral surface, and the top surface of the nut 13 is provided with a plus or minus groove 132 for a driver and a hexagon hole for a wrench. It is preferable to provide it.
